Faceted rock-crystal beads attributed to ca. 1550-1630 have been found at a number of North American archaeological sites, principally in the southeastern United Sates where they are generally termed Florida Cut-Crystal. Finds further to the north are rare. It was, therefore, of great interest to discover three different examples in the bead collections of two 17th-century Huron-Wendat sites in southern Ontario: Le Caron (BeGx-15) and Warminster (BdGv-1). The beads are investigated using a multi-disciplinary approach in an effort to determine how and where they were produced.
